i watched that first debate john kennedy on the stage with richard nixon and he was considered the winner of that on tv, not on radio, but that's where people were watching and then i think in 1976 in terms of a major gaffe when gerald ford who the president, hadn't been elected, richard nixon resigned, said that there was no domination by the soviet union of eastern europe. those are the two highlights, but that's a very rare occasion where a debate actually determines an election. >> let me ask you about this. both candidates seem to be praising each other lowering debate expectations. we're hearing mitt romney has been rehearsing zingers. the president has been rehearsing delivering shorter answers in this debate. what does each man need to do to convince the american public he's the right man for the job. let's start with president obama. >> president obama needs to just look presidential, not look flustered, not give any lines like hillary, you're likeable enough which seemed to demonstrate a certain arrogance or smugness or putting down anybody else. mitt romney has to be aggressive
